Problems with newer strike aircraft.

I found an article while following up on a thead here on the A7 Corsair II, apparently crews are suffering problems such as low tissue oxygenation during flights/missions and points out a reduction in the numbers of F-22 acquired. It seems this line of physiological concerns was the cause of the reduction in F22's acquired for service.
